CAR-WINDOW.

SPECIFICATION formingpart of Letters Patent No. 778,517, dated December27, 1904. Application filed March 25, 1904. Serial No. 199,893.

To @ZZ whom, t muy concern.-

Be it known that I, H ENRY F. VOGEL, a citi- Zen of the United States,residing' in the city ot' St. Louis, in the State of Missouri, havei-nvent- 5 ed certain new and useful Improvements in Car-IVindows, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

IO My invention relates to an improvement in the construction ot'car-windows,and has for its object to provide an arrangement wherebydust, air, and moisture may be more effectually excluded from theinterior of street- I5 railway cars than by the windows of such cars asheretofore made.

The invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claim.

2O Figure I is a vertical transverse section taken through a car-window.Fig. II is an enlarged vertical section taken through the upper portionof a lower window-sash and the lower portion of an upper window-sash.Fig. III

2 5 is a similar view to Fig. II, showing the upper window-sash in thesame vertical plane as the lower sash instead of being set at an anglethereto. Fig. IV is an enlarged horizontal section taken on line IV IV,Fig. I.

30 l designates a window-post having the sashrunway 2.

3 designates a lower sash the stiles of which operate in the runway Qand a corresponding runway in the opposing window-post.

I is the upper rail of the sash 3. The en- 35 tire lower sash may be ofany common shape.

Y 5 designates the upper window-sash. This upper sash has a lower rail6, that when the window-sashes are in elevated positions y mainlysui-mounts the upper rail of the lower 40 sash 3. The upper-sash lowerrail is cut away at 7, thereby providing a tongue or lip 8, that jutsdownwardly beyond the top edge of the lower-sash upper rail at itsexterior face, thereby preventing the passage ot' air, 45 dust, ormoisture between the opposing' sashrails to gai-n ingress into the carto which the sashes are applied. The upper sash may be set at an angleto the lower sash, as shown in Figs. I and II, or it may be in the samevertical 50 plane as the lower sash, as shown in Fig. III.

I claim as my invention- In a car-window, the combination with the lowersash, its sashway and upper rail, of the upper sash having in the innerside of its lower 5 5 rail a cut of a shape corresponding to the shapeof the upper part of the sashway for the lower sash, said cut forming insaid lower rail a tongue adapted to overlap the upper rail of the lowersash when the window is closed.
